On the section of Michigan Avenue known as “ Chicago’s Magnificent Mile” are buildings that resemble a string of pearls. Each pearl is a unique architectural delight
with its own history.

Perhaps one of the most unique pearls in the collection with a priceless historical value is the Tribune Tower. The Tribune Tower is described by one of its admirers
as an “ impulsive flame of beauty caught in a mold of stone”. Stones collected throughout the world are imbedded into the façade. This world-class collection of stones present themselves as witnesses and
ambassadors from places far away. Each stone in the Tribune Tower symbolizes an historical event in the timeline of humanity’s journey on our earth.

Many of the stones remind us of man’s highlights and achievements and some of the stones represent man’s darkest hours. There are stones from each of the 50 states of
the United States, there are stones from the Egyptian pyramids, the Taj Mahal, the Kremlin, Omaha Beach, Notre Dame and dozens of other places and locations of events that are coined into the books of
history.

One of the more unique stones is a piece of concrete from the Berlin Wall, the most awful and dreadful symbol of the Cold War. To anyone who was personal witness to
the Evil Empire, this stone represents the final hour of the Cold War and the first hour of the German unification.

The Berlin Wall had been erected August 13,1961 and was dismembered by the people on November 10,1989. One day later, on November 11,1989, Werner I. Juretzko suggested to the
Tribune Tower Management that a rock of the Berlin Wall should be added to the collection of historical stones.
